Pootling around on the 1952 BSA M33 today, saw that the rebuilt bridge over the Kok river at Sop Kok, SE of Chiang Saen on the 1129, is now open. There has been a detour here for a couple of years, around past Wat Prathat PaNgao and left onto the new 1063 superhighway. This would take you east over the "older" new bridge and up to the new traffic lights intersection and back on to the 1129 to turn right towards Chiang Khong. So, the old 2 lane bridge has been replaced by a bridge twice as big, 2 lanes each way. At present only 1 lane each direction is usable and it looks like a few months before it will be finished completely. Seems like a good business to be in at present, building road bridges.....
